Synthesis of Oligoparaphenylene-Derived Nanohoops Employing an Anthracene Photodimerization−Cycloreversion
Strategy.
J. Am. Chem. Soc. 2016;
138: 11144-11147
Key words
nanohoop - oligoparaphenylene - photodimerization - cycloreversion
Significance
Nanohoops composed of highly strained aromatic hydrocarbons are fascinating carbon-rich
structures, and creative strategies are required for their efficient syntheses. The
authors utilize an anthracene photodimerization–cycloreversion strategy to make a
novel nanohoop with interesting photophysical properties.
Comment
The rigid dianthracene scaffold approach generates the target nanohoop in excellent
yields over six steps. The often critical ring-closing step was achieved in a particularly
efficient manner under nickel-mediated Yamamoto coupling conditions.
